I bought this to substitute my more expensive Yves Rocher hair&nails pills, and after about 2 weeks it seems like they are working fine. I will probably continue to purchase this brand.
This product comes in a rather large bottle, which is less than halfway full, and stuffed with cotton balls. After fishing the cotton off the bottle, I still occasionally discover fluff from the pills. I don't know if this is common in the US, but personally I found it weird and misleading when it came to bottle size. The good news is that the pills are small and easy to swallow, fluff aside.
UPDATE: I got breakouts from this product for the first 2 weeks of use, but then my skin got better. Unfortunately I did not experience an increase in growth speed for my hair or nails, but I think my nails are a little stronger now.

This is my second time buying this but the first time I have bought it from iherb, which has the better price by the way. I bought this because my hair was falling out and it helped it stop falling out and improved thickness. It also made my nails grow. The only bad thing is that I have to take two tablets to really see any difference, maybe its just me, i don't know. Works though.

I have using this this since one month i am seeing different on my hair now its more thick and the hair fall less.. but i am afraid bcz of this i feel like my lungs heavy i am not sure cause of this . but now i reduced to half..

Really does speed up the growth of your nails and hair. I did not get to try it till the point where my hair thickens because within just 2 days of consuming just half a pill a day I broke out badly with huge cystic acne. Maybe I'll take a quarter of a pill once every 3 days...
